Create Individual Idocs Based on Parent and Child Segment type

Hi Experts,

I have a scenario IDOC to FILE ,  Split Single IDOC into Multiple IDOC's based on parent and child Segment Type

For example If 3 child segments are same and 1 segment is different under parent segment then 3 same child segments are clubbed and create single idoc under parent segments and 1 different child should create in individual idoc under parent segment.

Note : Same logic should work for N number of Parent Segments and Child Segments.

Outbound:

ZIdocName

Control Record

Data Record

Parent Segment A

   Child Segment 1

   Child Segment 1

   Child Segment 1

   Child Segment 2

Parent segment  B

   Child Segment 3

Status Record

I should get output like below

Inbound:

ZIdocName

Control Record

Data Record

Parent segment A

  Child Segment 1

  Child Segment 1

  Child Segment 1

Status Record

ZIdocName

Control Record

Data Record

Parent segment A

  Child Segment 2

Status Record

ZIdocName

Control Record

Data Record

Parent Segment B

  Child Segment 3

Status Record

Please suggest me step by step process to achieve this task.

Thanks.
